How to change the bulbs in the climate control for a 1999 Chevy trailblazer
Yes
your bulbs might be blown, if not, try your wiring harnes, see is it has nics or cuts in the wires. or you blew a fuse
High and low beams have differant filaments. You have to replace the bulbs.
9006 is the number...Wgner makes a great bulb....make sure the socket isn't melted, as Chevy can't seem to solve that problem.
try new light bulbs
Open the rear hatch and you will see the retaining screws inside the door frame.You can then drop the light out to get access to the bulbs. If no bulbs are bad then you may have a bad circuit board.
#1 blown fuse #2 brake pedal switch #3 light bulbs and/or sockets
Fuse or bulbs burned out. On most they are separate bulbs or high beam filament is broken if 2 in 1 bulbs.
Possibly the multifunction switch (switch in columm). Check the bulbs, fuses etc first
